Söchting Oxydator Mini
The Söchting Oxydator Mini is about the size of your thumb. It's designed for tanks up to about 8 gallons, but DiscoBee uses them in our 12, 20, and even 25G tanks with success. You can use additional Oxydators Minis for larger tanks if you wish. Includes 2 tiny pieces of catalyst and 2 x 75 ml containers of 4.9% Oxydator solution, and instruction sheet. Mini version uses 4.9% but you may also use food grade solutions which is readily available on such sites as Amazon. DiscoBee will carry refills in the short future.
The (2) 75ml bottles of 4.9% solution should last you approx 6months or more depending on the amount of oxygen in your water and water temps. Higher temps means less oxygen thus the Oxydator will do its job faster.
"Using a patented method, Söchting Oxydators produce normal and activated oxygen in the aquarium by means of Oxydator solution and special ceramic catalysts. The activated oxygen decomposes particularly putrid matters and toxicants and, thus essentially improves the well-being of fish and plants. Pure oxygen created by the Söchting Oxydator is mostly immediately dissolved in the water, so that there are hardly any bubbles produced. The oxygen supply is absolutely noiseless, expelling of CO2 and swirling of ground elements is avoided."
1 part 35% Hydrogen Peroxide to 6 parts distilled water yields the recommended 6% solution. For example: 1/4 cup of 35% Hydrogen Peroxide plus 1 1/2 cups of distilled water = 1 3/4 cups of 6% Hydrogen Peroxide
